According to some examples of the present disclosure, as shown in FIG. 3 to FIG. 4, the integrated module 1 further includes a switching valve 50. The switching valve 50 is arranged on the second flow channel plate 20, and the switching valve 50 is operated to allow the coolant to flow to the second heat exchange flow path or to prevent the refrigerant from flowing to the second heat exchange flow path. In some examples, the coolant flowing to the second heat exchange flow path can exchange heat with the refrigerant in the first heat exchange flow path, so that the refrigerant cools down the coolant. The switching valve 50 is operated to selectively switch the thermal management system 10000 to an appropriate working mode according to the heat dissipation requirements to meet actual differentiated needs. In some examples, the integrated module 1 further has a coolant circuit. The coolant circuit is configurable for heat exchange with the motor electronic control radiator 500.
